以下是一个简单的微信小程序与服务端进行socket通信的示例代码:
小程序端代码:
```javascript
const socketTask = wx.connectSocket({
url: 'wss://example.com/ws',
header: {
'content-type': 'application/json'
},
success: function () {
console.log('WebSocket连接成功')
}
})
socketTask.onOpen(function () {
console.log('WebSocket已打开')
socketTask.send({
data: 'Hello, WebSocket!'
})
})
socketTask.onMessage(function (res) {
console.log('收到服务器内容:' + res.data)
})
socketTask.onClose(function () {
console.log('WebSocket已关闭')
})
socketTask.onError(function () {
console.log('WebSocket连接发生错误')
})
```
服务端代码:
```javascript
const WebSocket = require('ws')
const wss = new WebSocket.Server({
port: 8080
})
wss.on('connection', function (ws) {
console.log('WebSocket已连接')
ws.on('message', function (message) {
console.log('收到客户端内容:' + message)
ws.send('Hello, WebSocket!')
})
ws.on('close', function () {
console.log('WebSocket已关闭')
})
})
```
这段代码中,小程序使用`wx.connectSocket()`方法连接到服务端的WebSocket地址,并监听WebSocket事件,当连接成功、收到消息、关闭WebSocket连接、连接发生错误时进行相应的处理。服务端使用`ws`模块创建WebSocket服务器,并监听WebSocket连接事件,当有客户端连接到WebSocket服务器时,也会进行相应的处理,包括收到客户端消息、发送消息和关闭WebSocket连接等。
